To the Editor: In their study, Dr Joensuu and
colleagues1 reported that cancerous tumors
detected by mammography screening have a lower risk of distant recurrence
and better survival than those detected outside of screening, independent
of the number of positive axillary lymph nodes, the primary tumor size, age
at cancer detection, histological grade, and other biological factors.
